To all whom it may concern."

Be it known that l, TnoMAs HOWARD SCOTT, a citizen of the United States, and a resident of Coatesville, in the county of Chester and State of Pennsylvania, have invented a new and llmproved Shuttle, of which the following is a full, clear, and exact description.

This invention has relation to shuttles designed for silk weaving machines and comtemplates more particularly an improvement in the tensioning means thereof.

At the present time in the common construction of shuttles thread guides are formed by straight pins set in the shuttle body, which pins are usually embodied. in the shuttle by drilling holes in the shuttle body part way through the same, fitting the pins in the holes and then filling in the exposed ends of the holes to cover the outer ends of the pins with was or any other suitable plastic material. In time the pins become worn by the thread and to remove and reinsert them in changed position, or to substitute new ins for the worn ones requires the services of a skilled mechanic. Furthermore the pins placed in the old Way work loose and cause in many instance serious damage or imperfection in the goods being woven.

lit is therefore the principal object of the present invention to provide an improved means for mounting the guide pins of the tension device within the shuttle body in order to effectually retain said pins against accidental displacement, in order to facilitate either removal and reinsertion in a changed position, or the substitution of new pins for the worn ones.

As a further object the invention con.- templates a guide pin mounting for the tension means of a weaving shuttle which is comparatively simple in its construction, inexpensive to manufacture and which is thoroughly reliable and highly edicient in its purpose.

lvith the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in'the-accompanying'drawings, it being understood that the right is reserved to embodiments other than those actually illustrated-herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.

In the drawings Figure 1 is a side view ot a shuttle equipped with a thread guide pin mounting constructed in accordance with the invention. i

Fig. 2 is an enlarged fragmentary plan view thereof, the same being illustrated in section approximately on the line indicated at 22 in Fig. 1.

Fig. 3 is a transverse sectional view taken approximately on the line 33 of Fig. 2.

Referring to the drawings by characters of reference, A designates the shuttle body, B and G the communicating recesses extending through the opposite sides of the shuttle body and within which the. tension means is mounted. A movable thread guide consisting of a lever D having a plurality of spacedeyes E is mounted in the recess B for swinging movement, the said lever being provided at its pivoted end with a bearing eye F and an actuating arm G which extends into the recess C and is connected by means of a tension element H to a in l for normally swinging the lever D in one direction. The stationary thread guiding means which consists of a plurality of pins J is in the present instance mounted in the recess B by means of a substantially u sha'ped mounting member '10 which consists of parallel upper and lower walls 11 and 12 connected by a bight or inner side wall 13. The upper and lower walls ll and 12 are provided with aligned apertures 14 and 15 for the reception of the guide ins J, the la ter openings 15 being close at their outer or lower ends by a flange 16 which is the reversely bent outer extremity of the lowerwall 12. The bight or inner side wall 13 extends only from the forward end of the mounting member 10 to awint medially of its length and is provide with an opening 17 which receives an attaching screw 18 anchored in the bottom wall of the recess B. The lower wall 12 projects at its rear end an appropriate dis tance beyond the rear end of the upper wall 11 and is suitably apertured to receive theretbrough the transverse screw 19 which extends through one side wall of the recess B and is anchored in the opposite side wall to constitute together with the screw 18 a means for retaining the mounting member tilt till

' eye l? of the lever D. After the stationary in place against movement and at the same time a bearing pin tor the bearing guide pins J are inserted in the aligned openings it and in the mounting member 10 the lower ends of thepins will rest upon the flange 18 and when the mounting memher is inserted in the recess B as illustrated in Fi s. 1 and 2, the extremities of the pins I D is then inserted through the recess (3 into til the recess B after which the screw 18 is inserted through the upper side wall of the recess B through the bearing eye F, the apertured rear extremity of the lower wall 12 or" the mounting member and finally threadedly anchored in the lower wall of the recess B. Under this construction and arrangement it will thus be apparent that the stationary thread guiding pins J are efiectually mounted and retained within the recess B of the shuttle against accidental displacement or movement which would tend to cause serious damage or imperfection in the goods to be'woven. It will be further apparent that the mounting member readily admits of removal of the pins for reinserting the same in changed position or for the substitution of new pins for the worn ones. The mounting member 10 is preferably stamped from a single sheet of material whichis then bent upon itself to the proper form for the completed device.

1 claim: v.

1 In a weaving shuttle, including a body having arecess for the accommodation of the tension device, means for'mounting the stationary guide pins of the tension device in the recess in said shuttle body, comprising a removable mounting member having spaced connected apertured walls within neonate which the opposite ends of said guide pins are received, and means on one of the walls of the mounting member for covering the outer ends of the apertures therein to provide a stop for preventing displacement of the guide pins therethrough.

2. In a weaving shuttle, including a body having a recess for the accommodation of the tension device, means for mounting the stationary guide pins of the tension device in the recess in said shuttle body, comprising a removable mounting member having spaced connected apertured walls within which the opposite ends of said guide pins are received, and means on one of the walls of the mounting member for covering the outer ends of the apertures therein to provide a stop for preventing displacement of the guide ins therethrough, the walls of the recess a utting the outer side of the oposite wall of the mounting member servmg to cover the outer end of the apertures therein to prevent displacement of the guide pins therethrough when the mounting member is positioned in the recess.

3. In combination with a weaving shuttle including a bodyhaving a recessed portion for accommodating the tension device, of means for mounting the stationary guide pins of the tension device in said recessed portion, comprising a mounting member of substantially U-shape in cross section and including spaced side walls having apertures therein for receiving the opposite ends of the guide pins. the connecting wall between the side walls receiving therethrough the anchoring means for retaining the mounting member within the recess, a flange on one of the side walls of the mounting member hent outwardly and parallel to the side wall to overlie and close the outer end of the apertures therein, one of said side walls being extended beyond the other and provided with an aperture for receiving therethrough the fulcrum upon which the movable guide element of the tension device is mounted.
